Patent number: 11562322Abstract: RFID systems may be configured to use session-dependent replies. When an RFID tag is involved in a certain inventorying session, the tag may respond to inventorying commands with a reply that is at least partly generated based on the session. For example, the tag may generate a reply with a string that has parity based on the session or includes an identifier for the session. The string may be a random number, a tag identifier or item identifier, or any other suitable data sent from the tag.Type: GrantFiled: December 28, 2020Date of Patent: January 24, 2023Assignee: Impinj, Inc.Inventors: Theron Stanford, Alberto Pesavento, Vadim Lobanov, Christopher J.

Publication number: 20220412998Abstract: Methods for performing procedures on single analytes at single-analyte resolution are disclosed. The methods utilize an iterative approach to performing a sequence of steps during a single-analyte process. Control of the single-analyte process is achieved by implementing actions during each iteration based upon one or more determined process metrics. Systems are also detailed for implementing the disclosed methods at single-analyte resolution.Type: ApplicationFiled: June 23, 2022Publication date: December 29, 2022Inventors: Vadim LOBANOV, Jarrett EGERTSON, Shunqiang WANG, Pierre INDERMUHLE, Gregory KAPP, Ryan SEGHERS, Siavash YOUSEFI

Publication number: 20060071759Abstract: RFID system components, such as readers and tags, communicate where the reader inventories a population of tags. The reader evaluates responses from tags by categorizing them in slots. As tags are inventoried, the number of slots based on a Q-parameter is reduced. The reader reduces the Q-parameter first in a first manner, then in a second manner where the second manner is different from the first manner. The first manner and the second manner may be different algorithms, different subroutines of an algorithm, or the same damping algorithm with different damping parameters.Type: ApplicationFiled: August 24, 2005Publication date: April 6, 2006Applicant: IMPINJ, Inc.Inventors: Scott Cooper, Christopher Diorio, Todd Humes, Vadim Lobanov

Publication number: 20060071758Abstract: RFID system components, such as readers and tags, communicate where the reader inventories a population of tags. The reader evaluates responses from tags by categorizing them in slots. As tags are inventoried, the number of slots based on a Q-parameter is reduced. The reader determines an interim value for the Q parameter, generates a Q1 value by applying the interim value to a damping function, and uses the Q1 value in another round of interrogation. The reader then determines whether to increase or decrease the interim value depending on the tag replies. The increase or decrease may be an increment or a decrement such as incrementing or decrementing a floating point number of the interim value in a damping function that is arranged to return an integer by rounding the floating point number.Type: ApplicationFiled: August 24, 2005Publication date: April 6, 2006Applicant: IMPINJ, Inc.Inventors: Scott Cooper, Christopher Diorio, Todd Humes, Vadim Lobanov

Publication number: 20050280507Abstract: An RFID reader inventories a population of tags. The reader evaluates responses from tags by categorizing them in slots. As tags are inventoried, the number of slots based on a Q-parameter is reduced. The reader addresses the tags by communicating a Q1 value for the Q parameter, generates first contents from replies received from the tags, and computes a first merit statistic based on the first contents. Then, the reader repeats the process with a Q2 value. Upon computing the first and the second merit statistics, the reader determines a Q3 value for the Q parameter. If the Q3 value is substantially equal to the Q1 value, the reader continues to receive the second replies without communicating the Q3 value. If the Q3 value is different from the Q2 value, the reader uses the Q3 value for another round of iteration heuristically converging on an optimum Q value.Type: ApplicationFiled: August 24, 2005Publication date: December 22, 2005Applicant: IMPINJ, Inc.Inventors: Christopher Diorio, Todd Humes, Scott Cooper, Vadim Lobanov

Publication number: 20050280506Abstract: RFID system components, such as readers and tags, communicate where the reader inventories a population of tags. The tags choose randomly one of a plurality of slots in response to each one of the values communicated by the reader and reply according to their chosen slot. The reader may initiate the inventorying by determining a Q-parameter value from a stored value and communicating the Q-parameter value to the tags. The reader may evaluate replies received from the tags in another plurality of tags, determine a second value from evaluating the second replies, and store the second value for future use.Type: ApplicationFiled: August 24, 2005Publication date: December 22, 2005Applicant: IMPINJ, INC.Inventors: Vadim Lobanov, Christopher Diorio, Todd Humes, Scott Cooper

As tags are inventoried, the number of slots based on a Q-parameter is reduced. The reader addresses the tags by communicating a Q1 value for the Q parameter, generates first contents from replies received from the tags, and computes a first merit statistic based on the first contents. Next, the reader determines a Q2 value for the Q parameter, which if used in the same way would meet a preset fairway condition better than the first merit statistic. After determining the Q2 value, the reader addresses a portion of the tags by communicating the Q2 value for the Q parameter.Type: ApplicationFiled: August 24, 2005Publication date: December 22, 2005Applicant: IMPINJ, Inc.Inventors: Todd Humes, Christopher Diorio, Scott Cooper, Vadim Lobanov
